    mantle in a round-bottom flask. A direct stem distillation took place‚ and the oil product was out aside for a week. After one week‚ the isolation of the eugenol actually takes place. Next the thin-layer chromatographic analysis takes place‚ but the experiment did not proceed to that step due to the incorrect amount of NaOH. Introduction The isolation of eugenol from cloves is isolated from ground cloves using the technique of steam distillation‚ which is often used to isolate liquid natural

    oils are often found in the intracellular spaces and glands of plant tissue. The oils may be located throughout the entire plant‚ but are often concentrated in the seeds or flowers of the plant. Many of the essential oils are steam-volatile and can undergo steam distillation to isolate the oils. Another method of oil extraction from these plants is through both solvent extraction and pressing methods. The functional group that is mostly responsible for the characteristic odors and flavors of fruit

    Objective The objective of this experiment is to perform a steam distillation using a microscale distillation apparatus and isolate a natural product from cloves. Introduction By performing steam distillation we can isolate eugenol at lower temperature than its usual boiling point of 248 degree Celsius. Eugenol belongs to a category called essential oil. Many of these compounds are used as flavoring and perfumes and in the past were considered the essence of plant from which they were derived

    manages the plant operation? (Start from process raw material fed into the process to its final state of production.) Process control system must be installed to make sure that distillation column to operate well for achieving required production rates and product quality. Current application for distillation control is based on linear controller such as Proportional (P) and Proportional-Integral-Derivative type controller. Each column has a control system made up of several control loops.

    and brought near to a boil. Due to the influential effect of hot water and steam‚ the essential oil is unbounded from the oil glands present in the plant tissue. The combination of water vapors and oil is condensed by indirect cooling with water. From the condenser‚ the distillate then flows into a separator‚ where the oil gets separated automatically. Plants are abundantly submerged in water‚ making a soup and the steam of this soup
